My small wishlist of mostly minor things/fixes:
Allow .PRG files to be loaded in VICE C-64 emu.
Update the ColecoVision emu ColecOD to allow hardware scaling for finer scaling on the RG350M 640x480 screen.
Make sound samples work on FBA-RG350
Fix the fullscreen scaling on Fceux to work properly on the RG350M.
Fix audio lag in XMAME.
Add LCD shader to Handy Lynx emu.
